The housing is formed with at least one through-opening forming a plug-in contact element holder for receiving the plug-in contact element. The plug-in contact element holder surrounds the plug-in contact element at least in regions. A seal is provided in the region in which the plug-in contact element holder surrounds the plug-in contact element so that the seal seals the plug-in contact element holder to the plug-in contact element. The plug-in contact element has a crimp section for establishing an electrical and mechanical connection to a cable, wherein the plug-in contact element is formed from a crimp element and a plug-in element, which are connected to one another by means of a press fit. ## Claims ### Claim 1 Plug-in connector, in particular for a high-current application, with an electrically conductive plug-in contact element and an electrically insulating housing, the housing having at least one through-opening forming a plug-in contact element holder for receiving the plug-in contact element, the plug-in contact element holder surrounding the plug-in contact element at least in regions and a seal being provided in the region in which the plug-in contact element holder surrounds the plug-in contact element so that the seal seals the plug-in contact element holder to the plug-in contact element, and the plug-in contact element having a crimp section for establishing an electrical and mechanical connection to a cable, wherein the plug-in contact element has a latching element and the corresponding plug-in contact element holder has a mating latching element so that the plug-in contact element is latched and held in the plug-in contact element holder to prevent a movement of the plug-in contact element counter to a plug-in direction, the plug-in contact element being formed from a crimp element and a plug-in element which are connected to one another by means of a press fit prior to insertion into the housing. ### Claim 2 (depends on 1) Plug-in connector according to claim 1, wherein the plug-in connector has a plurality of plug-in contact element holders, in each of which a plug-in contact element is arranged, and the plug-in contact element holders are sealed to the plug-in contact element. ### Claim 3 (depends on 1) Plug-in connector according to claim 1, wherein the seal is an O-ring. ### Claim 4 (depends on 1) Plug-in connector according to claim 1, wherein the housing has a plug-in surface which, when in a state connected to a mating plug-in connector, faces the mating plug-in connector, wherein a circumferential plug-in-surface seal is arranged on the plug-in surface and abuts on a corresponding mating surface in the plugged-in state. ### Claim 5 (depends on 1) Plug-in connector according to claim 1, wherein the plug-in contact element and the corresponding plug-in contact element holder have a positive fit so that the plug-in contact element is arranged in the plug-in contact element holder so as to be secure against rotation. ### Claim 6 (depends on 5) Plug-in connector according to claim 5, wherein the plug-in contact element has an approximately cylindrical section flattened with flat surfaces and the plug-in contact element holder is correspondingly shaped so that the positive fit is formed as a result. ### Claim 7 (depends on 1) Plug-in connector according to claim 1, wherein the plug-in contact element comprises a pin or a socket. ### Claim 8 (depends on 1) Plug-in connector according to claim 1, wherein the plug-in contact element has a cross-sectional region of at least 5 mm2 and preferably of at least 8 mm2. ### Claim 9 (depends on 1) Plug-in connector according to claim 1, wherein the crimp element has a cylindrical recess extending in the plug-in direction and the plug-in element has a correspondingly shaped cylindrical section, or vice versa, so that the cylindrical recess of the crimp element and the cylindrical section of the plug-in element are connected to one another via the press fit. ### Claim 10 (depends on 1) Plug-in connector according to claim 1, wherein a shielding housing element is provided, wherein the shielding housing element has an opening located approximately centrally in the plug-in direction, through which opening a corresponding pin can be inserted into a socket of the plug-in connector 1. ### Claim 11 (depends on 10) Plug-in connector according to claim 10, wherein the shielding housing element is formed from a metal sheet, for example zinc-plated brass, and wherein the shielding housing element in conjunction with a corresponding mating pin or a mating socket forms a shielding for the plug-in connector.
